PURPOSE OF REVIEW: Regional anesthesia is gaining attention as a valuable component of multimodal, opioid-sparing analgesia in cardiac surgery, where improving the patient's quality of recovery while minimizing the harms of opioid administration are key points of emphasis in perioperative care. This review serves as an outline of recent advancements in a variety of applications of regional analgesia for cardiac surgery. RECENT FINDINGS: Growing interest in regional analgesia, particularly the use of newer "chest wall blocks", has led to accumulating evidence for the efficacy of multiple regional techniques in cardiac surgery. These include a variety of technical approaches, with results consistently demonstrating optimized pain control and reduced opioid requirements. Regional and pain management experts have worked to derive consensus around nerve block nomenclature, which will be foundational to establish best practice, design and report future research consistently, improve medical education, and generally advance our knowledge in this vital area of perioperative patient care. SUMMARY: The field of regional analgesia for cardiac surgery has matured over the last several years. A variety of regional techniques have been described and shown to be efficacious as part of the multimodal, opioid-sparing approach to pain management in the cardiac surgical setting.
